10	GENERAL	Description Brief 2-3 sentence description of the purpose of the tool.	A visualization tool for coastal communities showing potential impacts from sea level rise and coastal flooding as well as a planning level tool.	An online mapping tool customized for local and state decision makers showing potential impacts from sea level rise and coastal hazards designed to help communities develop and implement solutions that incorporate ecosystem-based adaptation approaches	Searchable web tool providing 1) maps users can customize, embed, and download; 2) downloads: spreadsheets, slideshow-ready tables and graphs, and fact sheets; 3) individual community analyses; 4) area comparisons; 5) local sea level and flood risk projections. 100+ demographic, economic & infrastructure variables analyzed for 1000s of communities from zip code to statewide levels.	The Exposure Mapper tool aims to help communities discuss potential hazard impacts with flood hazard maps and community exposure maps showing people, places, and natural resources that may be exposed to coastal flooding.	Screening level tool to illustrate potential flooding and erosion with sea level rise intended to help address exposure and social/economic vulnerability to coastal hazards.	This tool displays an interactive map showing social indicators at the county level for all coastal counties in the U.S. Social indicators are numerical measures to describe the well-being (social, economic and psychological) of individuals or communities and are comprised of one or more variables combined into an index. These indicators characterize the level of dependence on commercial and recreational fishing for over 3,800 communities whereby an index score for any given community is relative to all communities included in the index. Index scores would differ with a more regional focus.	This tool allows users to find the rate shorelines are changing and to view historical shoreline positions and pentential impacts from SLR at a given location.	An online visualization and decision-support tool showing innundation from 1-meter of sea level rise specifically focused on the urban corridor of Honolulu as it represents the majority of the State's commercial and industrial sectors.	The FHAT is an informational mapping viewer that displays flood zones. The source of flood zone information contained in the FHAT is FEMA's Digital Flood Insurance Rate Maps (FIRMs).	The online tool is a GIS map portal comprised of flood and regulation data to provide partners with the ability to visualize and analyze flood prone areas and assess flood mitigation needs. Users can access flood history data, report a current flood event, locate property or watershed information, and access watershed and flooding reports. The tool is useful for both public awarness, and emergency action planning.

10	GENERAL	Top Three Strengths As succinctly as possible, list the top three strengths that make this tool unique.	1) Easy to use via Web browser, with GIS analysis results and map services available; 2) Uses consistent data sets and analysis for coastal areas nation-wide; 3) Includes photos and allows users to visualize impacts of sea level rise at known locations.	1) DESIGN: The tool has a modular, plugin architecture: Coastal Resilience “apps” can be developed by anyone and plugged into the web-based mapping platform. This allows developers to design a specific application to highlight a coastal management issue, respond to a disaster for post-storm decision making, or emphasize nature-based alternatives; 2) PERFORMANCE: Coastal Resilience 2.0 runs faster; operates on tablets; works nationally and globally; ... is open source, and it’s easy to share results and data; 3) PARTNERSHIPS: Developed among core partners including The Nature Conservancy, University of Southern Mississippi, The Natural Capital Project, NOAA Coastal Services Center, and the Association of State Floodplain Managers	1) Comprehensive tool providing exposure analysis, comparisons, and projections, as well as an interactive map. 2) Analyses cover ~100 variables, and conducted for 1000's of individual areas (zips, cities, counties, states, planning and legislative districts at all levels). 3) Local projections combine sea level rise and storm surge to give integrated risk estimates by decade.	1) Comprehensive flood hazard, societal vulnerability, and ecosystem exposure tool to aid cross-sector connections; 2) easy to share specific maps via links or downloads as well as step-by-step instructions for using in ArcGIS; 3) Includes Flood Hazards, High Tide Flooding, FEMA Flood Zones Storm Surge Scenarios , and SLR Scenarios all in one toolbar.	1) Significant improvement over the shoreline change tool in that this tool covers entire islands, includes options for innundation scenarios, and considers potential economic loss; 2) easy to use with clear explainations of the layers via the i button; 3) Users can drop a pin and/or get cursor locations	1) Easy to use; 2) in addition to displaying region of interest, users can see comparative data for surrounding counties; 3) there are 13 variables that users can select and display.	1) Shows parcel level details including TMK number, DFIRM, Transect ID, Shoreline change as a rate in ft/yr and Erosion Hazards; 2) Includes a historic shoreline layer; 3) easy to print reports	1) Very simple and easy to use and includes cursor location in degrees; 2) Includes a critical infrastructure layer; 3) It is possible for user to visualize worst case scenarios using the combined innundation layer	1) Simple to use; 2) can generate customized Flood Hazard Assessment report (single page .pdf); 3) provides access to related resources (street view, property tax, flood insurance information, and floodplain regulations) without need to duplicate location search.	1) Over 55 option for user defined map layers including USGS Gages, Current Flooding, Flood Predictons,Live Radar, NFHL, Parcel and Zoning, Water Resource Point, Water Resourse, Land Use, NWS Wathces and Warning, Hazards, and Soil Layers; 2) Users can report a current flood event; 3) Queries can be performed at the TMK parcel level or by watershed for property information including flood hazard risk, soil drainage and erosion properties, tsunami evacuation zone, and watershed documents
10	GENERAL	Top Three Limitations As succinctly as possible, list the top three weaknesses or limitations that coastal planners or managers might encounter using this tool.	1) Inundation scenarios do not include coastal storm surge, erosion or other coastal processes such as changes in coastal geomorphoology; 2) Cannot customize outputs or load additional local inputs directly into the tool; 3) Appropriate for use as a screening-level or planning tool allowing zoom in scale of approximately 1:18,055.	1) ONLINE-ONLY: No ability to access the tools with limited or lack of connectivity; 2) USER-FRIENDLINESS: Not catered to general public, so training is requirement to engage stakeholders so they can fully utilize the tool and understand the data and analyses; 3) COMMUNICATIONS: With so many tools now available on the web, it is hard to decipher the niche and therefore use of this tool relative to others that address similar issues	1) Map should not be used for site-specific decisions (supplement with direct field measurements of elevation), as wider-area analyses are more robust than point-by-point mapping; 2) Levee data are incomplete, and maps/analyses incorporating levees assume condition good and heights infinite; 3) No physical modeling of storm surge or waves on top of sea level rise.	1) Users cannot control SLR scenarios; 2) Communities might not have access to arcGIS; 3) Cannot display more than one layer at a time	1) There are 31 possible layer selections but difficult to view more than one layer at a time; 2) No option to print or share map with user defined layers; 3) Some layers like economic loss appear as large pixels (boxes) which may make it difficult for planners or developers to consider seriously (Note - innundation presented in feet while other tools present in meters)	1) Map products are not available for download or for sharing; 2) Human Dimension data last collected in 2011 and the census data is from 2005-2009 meaning these data could be outdated given rapid changes in urban development; 3) the county level data may be too broad to implement any community level action.	1) Not intuitive, for example, the confidence layer could use more explanation and the innundation colors are not explained - example with 1 foot of SLR some areas are shaded green and green is listed as "Ground"; 2) Cosmetics - Historic shorelines are difficult to see and layers should have transparency options; 3) Transect data from 2012 - may be outdated	1) limited to 1-meter innundation; 2) there are no options for users to download or share their maps; 3) Socioeconomic data used in the study is not shown in the mapping results	1) Does not identify all zones subject to flooding; 2) rendering is slow and map quality is poor (misaligned layers, cannot read labels at certain scales, outdated imagery); 3) property addresses need to be kept up to date.	1) Not clear if real-time data is updated for immediate access; 2) the map is technical and may be intimidating to non-GIS experts/regular users (i.e. general public); 3) clicking additional buttons at the top of the map such as document library or regulatory guidance are not related to the map directly and take users out of the map - would be better to open a new browser tab when clicked.
